Among the Three Kingdoms, Sun Wu occupied most of Yangzhou, Jingzhou, and the whole territory of Jiaozhou. It is bounded by the Yangtze River and huaihe river in the north and the Han River and the Yangtze River in the west; the Three Gorges of the Yangtze River in the west; the East China Sea in the east and the central part of Vietnam in the south. Eastern Wu was the longest ruling regime in the Three Kingdoms and the last to perish in the Three Kingdoms. After a total of 4 emperors ruled, he enjoyed 51 years of the kingdom; from Sun Quan's title of King of Wu, it was 58 years; if you count from the beginning of Sun Ce's crossing of the river, Sun Wu's royal family ruled Jiangdong for a total of 85 years.
In the first year of the Huanglong Dynasty (229, the third year of Wei Taihe, the seventh year of The Shu Han Jianxing), Sun Quan was proclaimed emperor, the state name was Wu, and the yuan was changed to Huanglong.
In the fourth year of Chiwu (241), Sun Quan's thirty-three-year-old eldest son, the crown prince Sun Deng, died, dealing a severe blow to Sun Quan. Before his death, Sun Deng wrote to Sun Quan, suggesting several ways to make the country stable and prosperous, and recommended a number of excellent courtiers, hoping that Sun Quan could appoint them to make the State of Wu strong. It is said that when Sun Quan saw this article, he couldn't help but weep with sadness.
Sun Deng is a very talented person. Sun Deng's brother Sun Wei died, and Sun Quan felt sad and reduced his diet. Sun Deng rushed to persuade Sun Quan not to be too sad, so as not to affect the country. Sun Quan accepted and increased the diet. More than ten days later, Sun Quan wanted to send Sun Deng back to Wuchang, but Sun Deng wanted to stay with his father, so Sun Quan dispelled his thoughts and let Sun Deng stay with him. Sun Quan attacked the new city of Hefei, which was occupied by the State of Wei, and ordered Sun Deng to stay behind and manage the affairs of the rear. At that time, the crop harvest was not good, and the number of thieves increased, so Sun Deng formulated an order law to deal with the thieves and obtained good results.
Sun Deng is very sympathetic to others. For example, when Sun Deng went out hunting, he could have walked close to the path path, but he went around and avoided the fields so as not to damage the farmers' crops; when resting, he only chose open space. In addition, once riding out on horseback, there was a projectile flying by, the entourage looked for who to fire, and finally found a person with a slingshot and a projectile, everyone thought that he did it, but the man did not recognize it, the entourage wanted to teach him a lesson, Sun Deng did not allow it. Sun Deng compared the projectile that the man was holding with the projectile he shot, and found that it was not the same, proving that the projectile was not fired by the person, so he released him. Another time, the golden horse bowl used to hold water was missing, and Sun Deng knew that it was done by the attendants around him, and he could not bear to send them to punish, but only scolded them, sent them back to their hometown, and ordered those close to him not to say it.
Sun Deng is very filial and generous. Because Sun Deng was born to Shu, Lady Xu raised him as an adoptive mother and was kind to him. Later, Lady Xu was deposed because of jealousy and exiled to Wu County. At that time, Sun Quan favored Lady Bu, and what she rewarded Sun Deng, Sun Deng only thanked and did not dare to accept. The clothes sent by Mrs. Xu were bathed before being put on. When Sun Deng was made crown prince, he asked Sun Quan to make Lady Xu empress, but Sun Quan wanted to make Lady Bu empress, but in the end he did not agree. When Sun Quan planned to send him back to Wuchang, Sun Deng also asked for himself to stay and do filial piety for his father.
After Sun Deng's death, the position of crown prince was suspended, and Sun Quan's second son Died even earlier, Sun Quan had to appoint the eldest third son and grandson as the crown prince, and the fourth son and grandson as the king of Lu, which triggered the "second palace dispute" that led to the weakening of the Wu state, also known as the "Southern Lu Party Struggle".
Because Sun Quan was very fond of Sun Ba, he was very pampered, and there was no difference between his treatment and that of Prince Sun He, so Sun Ba had the heart to seize the reserves and privately spread the gossip of the prince, and eventually Sun He fell out of favor. Just when his son was fighting for the throne, in the thirteenth year of Chiwu (250), Sun Quan deposed Sun He, killed Sun Ba, and made the seventh Sun Liang crown prince.
Although the Dispute of the Two Palaces ended, many ministers such as Wu Yue and Lu Xun died as a result, and finally more than a dozen officials who advised Sun Quan to kill Sun Ba and exile Sun He were also convicted, and all kinds of killings and punishments derived from the Dispute Between the Two Palaces dealt a great blow to Sun Wu's talents, and during the period Sun Wu's political situation was also affected by the division of the dynasty. Sun Luban, Sun Jun, Sun Hong, Lü Dai, and Lü Zhao, who originally supported Sun Ba, were also not liquidated. Later, Sun Quan repented and wanted to recall Sun He and restore him as crown prince, but because Sun Luban, Sun Jun, and Zhongshu Ling Sun Hong resolutely opposed it, they did not succeed, and only made Sun He the King of Nanyang.
In 252, Sun Quan, who had been in charge of Jiangdong for fifty-two years, died at the age of seventy-one. Sun Liang succeeded to the throne at a young age, and was assisted by the edict of the eunuch Zhuge Ke, but before he took the throne, sun Hong and Zhuge Ke clashed, and then there were many coups and mutinies, Sun Liang was deposed as the prince of Huiji, and Sun Xiu was made emperor. After Sun Xiu's death, the throne returned to Sun He's lineage, and Sun He's eldest son, Sun Hao, took the throne.
At the beginning of Sun Hao's reign, he once practiced benevolent government, ordered to care for the people in the country, and opened a warehouse to revitalize poverty, reduce the number of harem palace women, and release the surplus rare animals and animals in the palace, and was once known as the Ming Emperor. However, with the passage of time, his brutal side gradually began to reveal, becoming a famous tyrant in Chinese history. He was suspicious and cruel by nature, and he inflicted many tortures. He had killed or exiled a number of important clans, such as killing his brother Sun Feng, exiled his brother Sun Ji and Sun Yi, killed his fifth uncle Sun Fen and his five sons, and killed his half-brothers Sun Qian and Sun Jun. He also often inflicted heavy sentences on his ministers, taking only officials at the level of chancellor as an example: except for Zhang Ti, who died in battle at the time of the fall of the country, Puyang Xing was exiled, the Yisan clan, Wan Yu was condemned to suicide, and the whole family was exiled; a few years after Lu Kai's death, the whole family was exiled. In addition, Sun Hao was very superstitious, often relying on reasons such as fortune, hope, divination, and Weiwei to decide on major events such as moving the capital, employing soldiers, and abolishing the empress, and therefore always firmly believed that he would unify the world.
Eventually, in 280, Sun Wu's regime died in the Western Jin Dynasty.
